How does Christina Aguilera feel? Well, she should feel fantastic! The 32-year-old singer showed off her amazing weight loss and svelte body on The Voice Monday, Nov. 4. Aguilera teamed up with rapper Flo Rida to perform their new single, "How I Feel," and the songstress slipped into a sheer bodysuit before taking the mic.

At the beginning of their number, Aguilera styled a low-cut black blazer, rhinestone nude tights and black top hat. Midway through the song, however, the singer removed her blazer to reveal she was actually wearing an ultra-sexy, see-through bodysuit that exposed her black bedazzled bra and tiny shorts underneath. Looking confident and better than ever, Aguilera strutted across the stage while belting out her hit song.

While taking last season off from the show, Aguilera drastically slimmed down. "It's more of a mind-body thing for her," a source previously told Us Weekly of Aguilera's workout and diet plan. "She believes in exercise that she enjoys, doing strength work as opposed to intense cardio."

During an appearance on The Tonight Show with Jay Leno on Monday, Oct. 28, Aguilera's fellow Voice mentor Adam Levine commented on her weight loss. "Christina seems happier this year," host Jay Leno noted. "Is that my imagination or do you sense that?"
